Potassium Nutrition in Vegetables

Abstract

India is the second largest producer of vegetables in the world, next to China. In spite of this, the dietary recommendation of vegetables is not available to all. Amongst various reasons for poor yield and production of vegetables in the country, the poor nutrient management is imperative. Fertilizer application to most of vegetables is arbitrary and often erratic. In view of the growing importance of vegetables, the adequate fertilizer management is of special importance. Potassium is the third major essential plant nutrient along with N and P. It is essential for the growth and development of all plants and animals. Among other nutrients, vegetables crops in general remove much higher quantities of potassium and usually carry high amount of potassium in the marketable parts. Hence, a rational fertilizer management in vegetables ensures the proper supply of potassium for sustained productivity and better quality of crop produce. The application of potassium is responsible for quality products of fruits and vegetables through an increase in sugar contents of crops, plays an important role in photosynthesis and increases water use efficiency. Besides, it also safeguards best monetary returns from all possible ways.
